Abstract: Presented is a precision power saw assembly which includes a saw table manufactured to exceedingly close tolerances and on which a circular saw blade and its driving apparatus is suspended. The saw blade is mounted for horizontal translation from one end of the saw table to the other together with its driving motor. A stop plate adjustable to close tolerances is mounted on the top of the saw table and provides an abutment against which the edge of a workpiece may abut. Additionally, a multiplicity of fluid operated clamps are provided to clamp the workpiece in proper position and retain it in such position during the entire cutting operation.
